AB  - DNA sequences of multiple copies help in understanding evolutionary mechanisms, 
      genomic structures and karyotype differentiation. The current study investigates 
      the organization and distribution of different repetitive DNA in the standard 
      complement and B chromosomes in Astyanax scabripinnis (Jenyns, 1842) chromosomes 
      from three allopatric populations in Campos do Jordao region, Sao Paulo State, 
      Brazil. The location of microsatellite sequences showed different chromosome 
      distribution between Lavrinha Farm Stream (LFS) and Lake of Pedalinho (LP) 
      populations. However, the karyotype of these populations basically followed the 
      pattern of dispersed distribution in the A complement, conspicuous in 
      telomeric/interstitial regions and preferential accumulation in the B chromosome. 
      The B chromosome showed heterogeneous location of microsatellite probes CA, CAC 
      and GA. The H3 and H4 histone genes were isolated from the total genome of the 
      species and then the chromosomal mapping was performed by fluorescence in situ 
      hybridization (FISH). The FISH signals showed high similarity for the probes H3 
      and H4 mapping in genomes of the populations analyzed. The sequences (GATA) (n) 
      revealed a sex-specific trend between the chromosomal location in males and 
      females at (LFS) and (LP) populations. Although species that comprise the 
      Astyanax scabripinnis complex do not have morphologically differentiated sex 
      chromosomes, the preferential GATA location - sex-associated - may represent a 
      sex chromosome in differentiation.
